A CORPORATION or WRITING-ADDING MACHINE.

Specification of Letters Patent. Patented Feb. 1'7, 1920.

Application filed November 4, 1912. Serial No. 729,384.

To all whom it may concern Be it known that I, HARRY ARTHUR FOOTHORAP, a citizen of the United States of America, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Writing-Adding Machines, of which the following is a specification. v

This invention relates to writing adding machines of that type which embraces a typewriter and an adding mechanism.

The object of the invention is to produce a machine of the specified character equipped not only for column addition but also for cross addition known as cross-footing and also for grand totalizing, which is a mere continuation of the cross-footing operation to compute the grand total of several parallel columns, the column adding devices being stationary and the'cross-footing or grand totalizing device being movable to successive column positions for operation in conjunction with successive column adding devices.

More specific objects of the invention will appear as the necessity for their accomplishment is developed during the progress of the succeeding description. 7

In the accompanying drawings Figure l is a plan view of a portion of an Elliott-Fisher billing machine; equipped in accordance with my inventiom Fig. 2 is a rear elevation thereof.-

Fig. 3 is a sectional view of the machine with certain parts omitted.

Fig. 4 is a section on the line 4-4 of Fig. 2 looking in the direction indicated by the arrows. Y i Fig. 5 is a rear'elevation of the crossfooter advancing mechanism in normal position.

Fig. 6 is a similar view of the same parts shown in the positions they occupy after limited initial movement of the cross-footer advancing arm or crank, the lock being shown released to advance the cross-footer upon continued movement of the crank.

' Fig. 7 is a similar view with the parts in the position theyassume at the end of the cross-footer advancement,

Fig. 8 is a view of the same mechanism with the parts inthe positions they assume upon complete retraction of the cross-footer.

Fig. 9 is a perspective view of the cross footer carriage and adjacent parts.

Fig. 10 is a front elevation of the crossfooter controlling device.

Fig. 11 is a detail sectional view of the device shown in Fig. 10.

Fig. 12 is a detail view of the extension bearing bracket for the actuator shaft, and

Fig. 13 is a detail perspective view of the frame extension plate.

Each part is indicated by its appropriate reference character throughout the views. 1 indicates the frame and 2 the carriage of an Elliot-Fisher billing machine in which, as "is well understood, the frame moves longitudinally of the platen, not shown, to

line space the writing while the carriage 2 moves transversely of the platen on the frame 1 to letter space the writing. The

keys s3 operate the downwardly acting printing mechanism 4 and the numeral keys operate through suitable intermediate connections 5, an actuator or master wheel 6 carried by an actuator shaft 7 Supported by the frame 1 in rear thereof,

is what is known as a register bar 8 upon which are adjustably supportedv a plurality of, column registers 9 so located that when the printing mechanism is in position to priht in a given column on'the work sheet, the master wheel or actuator 6 will be disposed in cooperate relation to the particular column register appropriated. to such column. Each of the column registers. includes a series of denominational members, carrying mechanism, a device for resetting thecarrying 'mechanism upon the retraction of the carriage 2 and a resetting lever by means of which the denominational members and the carrying devices as well may be reset to normal zero position. Therefore it is merely necessary to operate the typewriter in the usual-manner '00 print a number in any desired column, the movement of the carriage incidental to the writing of such number serving to bring the actuator 6 into cooperative relation with the proper denominational members of. the

registers and the rotation of the master wheel upon the depression of the keys to.

print, serving to rotate thedenominational members to an extent corresponding to the values of the keysdepressed.

The carriage 2 is under the control of the keys and is drawn to the right by carriage propelling mechanism including spring drums 10 carried by the frame 1 and connected to the carriage by tapes 1,1. The described mechanism is of ordinary and well known construction being exemplified in Patents Nos. 573,868 to R. J. Fisher and 829,971 to Laganke and Smith.

The cross-footer attachment with which my present invention is more particularly concerned is mounted at the right hand end of the machine and c'omprehends a crossfooting and grand totalizing register 12 similar in construction to the registers9 and designed to be operated by a second actuator or master wheel 13 mounted on an extension 14 of the shaft 7 beyond the right hand end of the carriage. The actuators 6 and 13 being secured to the same shaft are operated in unison and are so spaced that they will simultaneously engage corresponding denominationalmembers or number wheels of a column register 9 and the cross-footing register 12. (See Fig. 1.) Thus upon the depression of a key the two registers will be simultaneously operated in corresponding degree to accumulate the same value.

The cross-footing register 12, unlike the column registers 9, each of which appropriated to a particular column and none other,

, is designed to accumulate values printed in different column positions. For instance, in cross-footing the cross-footer 12 must accumulate the several values printed inv the several colums and accumulated in the sev- .eral column registers so as to compute and register what is known as the cross-footing, to wit, the total value of numbers printed in a horizontal row but in difierent column positions. Therefore, instead of remaining stationary with respect to transverse movement relative to the work sheet, as do 'the column registers 9, the cross-footing register 12 is mounted to move to different column positions so that after a number has been printed in a given column and accumulated in both a column register and the cross-footer, the latter will be moved to another column position so that when a succeeding number is printed in another column and accumulated in another column register, it will also be accumulated in the crossfooter.

To accomodate the cross-footer, the frame 1 of the machine is equipped with a frame extension 1 at the upper end of which is a bracket 15 supplementing the two usual rear frame brackets 16 and 17, at the upper ends of which the register bar 8 is ordinarily mounted. Extending between the brackets short register supporting bar 8 slidable along the guide bar 18. Upon this short register bar 8, the cross-footing register 12 is adjustably secured just as the column registers 9 are secured to the bar 8. The carri'age 20 also includes a stem 20 having a bifurcated upper end 20 to engage the head 20* 'and fixed at its lower end to a guide bar 21 slidable in suitable bearings 22 carried by the brackets 15 and 16. The cross-footer carriage 20 is thus properly guided in its movement to advance the crossfooter 12 to different column positions.

In the present embodiment of the invention, it is designed to lock the cross-footer carriage in its column position and to provide manually operated means operative to first unlock the carriage and then shift the 'its under side with long ratchet teeth 25.

The notches 21 and teeth 25 are spaced to correspond with .the adding fields or columns. and co-operating with the notches 24 is a locking arm 26 mounted to swing from the upper end of a bracket 27 extended rearwardly from the frame of the machine. The

lockin arm 26 is yieldingly' urged toward its 100 ing or engaging position by a spring 28 secured to the free end of the arm and to the bracket 27, as clearly shown in Fig. and the end of said arm normally engages one of the notches 24 of the locking bar 23 to hold the latter rigidly against movement in either direction. Extended from front to rear of the machine and journaled in suitable bearings is a rock shaft 29 equipped at its front end with a crank 30 and'having at its rear end a driving arm 31 upon which is pivotally sup? ported a drivin pawl 32 adapted td-engage thelr'atchet teet 25 of the bar 23 and yieldingly urged toward the bar by a spring 33 secured at one end to the arm 31 and at its opposite end to the tail piece 34. of the position of the parts the driving pawl 32- is disposed a slight distance in rear ofthe vertical face of the adjacent ratchet tooth, this relation of the parts permitting slight movement of the arm 31 before the pawl engages the tooth. (See Fig. 5). This lost movement is utilized to release the lock 26. At the upper end of the driving arm 31 is pivotally secured a releasing cam 35, the upper end of which is designed to engage a pin 36 projecting from the arm 26 and serving also as a point of attachment for the spring 28. The lower end of the'r'eleasing cam is urged by a-spring 37 into engagement with a stop 38 on the driving arm 31, the pintle of the pawl 32 serving as such stop in the present construction. It will thus be seen that the releasingcam 35 is fixed against, swinging movement in one direction relative to the driving element 31 but is capable of such swinging movement in the opposite direction against the resistance of the spring 37.

In the normal position of the parts shown in Fig. 5 the locking arm 26 is engaged with the bar 23, the beak of the driving pawl 32 is a slight distance in rear of the next succeeding ratchet tooth and the upper end of the releasing cam 35 is directly under the pin 36 of the locking arm. If now the shaft 29 is rocked-by the manipulation of the crank 30, the initial movement of said crank will cause the releasing cam 35 to raise the locking arm 26 out of engagement with the bar 23 and to simultaneously advance the driving pawl 32 into engagement with the adjacent ratchet tooth 25. The continued movement of the crank will now swing the driving arm 31 which,

through the pawl 32, will advance the bar 23 and with it the cross-footer carriage 20 and cross-footer 12 to the next column positions Before this position is reached, however, the releasing cam 35 will have moved out from under the pin 36 and the locking arm 26 will rest upon the upper edge of the bar 23, ready to be drawn into engagement with the next succeeding notch 21 to accurately locate and lock the cross-footer in the next column position. As soon as the lock 26 snaps into its locking position, the crank 30 is released by the operator and is returned together with the parts secured thereto, to normal position by a retracting spring 39 secured, as for instance, to the hub of the driving arm 31 and to the bracket 27. I

The limits of the normal stroke of the driving element 31, just described, are defined by stops 10 and 11 formed in a plate 12 and engaged by a spring pressed stop 13, carried by the handle 11 of the crank 30. The stop 13, carried by the cranlqis normally disposed to engage the two fixed stops 10 and 11 but may be withdrawn from such of the parts, Fig. 6 showing the positions assumed by the parts when the lock has 4 been released and the driving pawl brought into engagement with a ratchet tooth, and 30 Fig. 7 showing the positions assumed by the parts when the stroke has been completed and the locking bar, carriage and crossfooter relocked in the new column position. Fig. 5 also shows, of course, the positions reassumed by the parts upon the release of the crank and the retraction of the mechanism to normal position preparatory to a repetition of the cross-footer advancing operation. j

\Vhen the cross-footer has reached the limit of its advance, it is of course necessary to retract it again to the first-column position so that as succeeding numbers are written in the columns, it may again accumulate and register the cross-footing or the sum of two or more cross-footings as the case may be." To effect this retraction of the crossfooter, I provide a cross-footer retracting motor 17 which, in the present instance, is in 100 the form of a spring drum carried by the frame of the machine, as shown in Fig. 2, and connected as by a metal tape 18 with'the bar 23. -When the cross-footer has advanced interference with this retractile movement.

For this purpose provision is made for what may be termed an extraordinary movement of the crank 30, that is to say, a movement somewhat beyond the limit of its normal re traction. To accomplish this it is simply necessary to draw back the stop 13, carried by the crank, out of interfering relation with the upper fixed stop 10 and then swing the crank 30 to the position indicated in Fig. 8. This backward movement of the crank 30 from normal position accomplishes the complete release of the lock 26 and driving pawl 32 from the combined locking and ratchet bar 23. This release of the bar 23 from the lock 26 is effected by what maybe termed an unlocking cam or a lock releasing cam 19 mounted at the upper end of the driving arm .31 in such po- 13!) 'sition that it remains out of interfering re the cam l9 will be in close'relation to the pin 36 projecting from the locking arm 26. Therefore, when the operating handle 30 is carried back beyond its normal retractingposition, shown in Fig. 5, to the releasing position shown in Fig. 8, the cam 49 will ride under the pin 36 to lift the locking arm 26 out of engagement with the bar 23. The

same releasing movement of the operating handle will cause the driving arm 36 to carry back the driving pawl 32 and will cause its tail piece 34 to contact with a re leasing stop 50, which is secured to the bracket27. When the movement of the tail piece is thus arrested, slight continued movement of the driving arm 31 will cause the driving )awl 32 to swing on its axis and to be entirely withdrawn from interferin relation with the teeth 25'of the bar 23. Tt will be understood, however, that the driving pawlwill clear the teeth before the bar 23 is fully released from the lock 26 so that the instant said bar is released it may be fully retracted by the motor 47 to the position shown in Fig. 2 to restore the cross-footing register 12 to its normal or first column position. The handle 30 may then bereturned to normal position, shown in Fig, 5, but the locking of the register in its first position by the arm 26 is not necessary, as it is securely held at the limit of its movement by the motor. The first operating movement of the handle may be from the position shown in Fig. 8 inwhich case the initial movement would merely be utilized to restore the operative relation between the bar 23, locking arm 26 and the driving pawl 32 and continued movement of the handle will effect the advance of the register 12 in the manner heretofore described.
